I have 4 hens (Golden Buffs), received them as day old chicks on 31 Oct 14 and got my first egg on Feb 15th 2015. Only one hen is laying, but that's only 3 1/2 months from hatch to egg. Isn't that early? I thought they started laying at 5 months. Again only one is laying, getting 6 eggs per week. About a 25-27 hr cycle, takes a day off. My other 3 hens haven't produced anything yet.
I would size the eggs as small, except for 1 that was large. Do I have an early egg layer?
15 1/2 weeks is early, but not unheard of. My first egg was from a 16 week Cuckoo Marans.
